Jeremiah 15:16 Thy words were found, and I did eat them, And thy word was unto me the joy and rejoicing of mine heart; For I am called by thy name, O LORD God of hosts.
I do not know how I could ever say enough to you about the need to get into the Word of God itself. Devotionals that others write are well and fine but never take the place of the Word of God. Every Christian ought to develop the habit of reading the Bible. Everyone ought to try to learn something new every day. All should want to hear God speak. He has spoken in His Word. You can hear it and understand it.
It will give you joy that no other book can give you. It will cause you to love Him more if you learn to read what God Himself has said.
